HUB FOR VEHICLES.

SPECIFICATIQN forming part of Letters Patent No. 764,593, dated July 12,1904.

Application filed April 25, 1904.

To all whom it may concern..-

Be it known that I, OMAN E. JOHNSTON, a citizen of the United States,residing at Bellevue, in the county of Huron and State of Ohio, haveinvented certain new and useful Improvements in Hubs for Vehicles; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the figures of referencemarked thereon.

The present invention relates to improvements in hubs for vehiclesespecially designed to be mounted upon an axle and held in properposition without the use of an external nut or other fastening device.

Figure 1 is a horizontal section of the hub and the different partsbelonging thereto, showing the same mounted upon an axle. Fig. 2 is aside elevation showing the hub properly mounted upon an axle. Fig. 3 isa view showing a portion of the axle, the axlebox, the hub-retainingdisk, and the couplingnut located thereon, but disconnected. Fig. 4 is adetached view of the hub-retaining disk, showing the same separated.Fig. 5 is a view showing a portion of the coupling-nut, also a portionof the hub-retaining disk in relative position with the coupling-nut,and also showing a set-screw.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanyingdrawings, 1 represents the vehicle-axle, which isconstructed in the ordinary manner, except that the outer ends of saidaxle are non-screwthreaded.

The axle 1 is provided with the usual collar 2, which collar is for thepurpose of preventing any longitudinal movement of the hub after the hubhas been properly connected, as hereinafter described.

Upon the axle 1 is mounted in the usual manner the axle-box 3, whichaxle-box is located in the hub 4 and concentrically therewith.

For the purpose of causing the axle-box 3 to rotate with the hub saidaxle-box is provided with the short ribs 5, which ribs are Serial No.204.687. (N model.)

seated in the recesses 6, formed in the inner periphery of the hub.

For the purpose of holding the hub upon the axle-box at the outer endthe ribs 7 are 7 will press or bear against the inner periphery of thehub.

For the purpose of providing the oil-chamber 8 the ribs and 7 are formedof such a width that the outer periphery of the axlebox' 3 and the innerperiphery of the hub 4: will be spaced from each other, as illustratedin Fig. 1.

For the purpose of supplying oil to properly lubricate the bearing theaperture 9 is provided, which aperture is to be closed by means of theset-screw 10, which set-screw serves the double purpose of closing theoilaperture 9 and assisting in holding the axlebox 3 andthe hub 4. infixed relative position.

It will be understood that the location of the aperture 9 and theset-screw 10 is imma terial, as their only purposes are to provide meansfor the introduction of oil and at the same time seating theset-screw 10against the axle-box 3, thereby preventing any relative movement, asbetween the axle-box and the hub, by reason of any slight imperfectionin the mechanical construction of the different parts. 7

The rear or inner end of the hub 4 is screwthreaded upon its outerperiphery, as illus trated in Fig. 1, said screw-threads being for thepurpose of engaging the screw-threads formed upon the inner periphery ofthe coup ling-nut 11, said screw-threads so engaging the screw-threadsformed upon the hub being formed upon the larger inner diameter of saidcoupling-nut.

The coupling-nut 11 is provided with the shoulder or flange 12, whichshoulder or flange is adapted to abut against theinner end of theaxle-box 3 or against an intervening washer, as the case may be.

The coupling-nut 11 is provided with screwthreads 13, formed upon theinner periphery of the small diameter of said coupling-nut, whichscrew-threads are for the purpose of l holding or assisting in holdingthe hub reprovided, which ribs are so formed that they taining disk orring 14 in adjusted relative position with the coupling-nut 11.

The inner end or portion of the couplingnut 11 is provided with theflange 15, which flange is so formed that the opening of the nut 11 willbe substantially of the same diameter as the diameter of the collar 2and is so formed for the purpose of allowing the coupling-nut 11 to bepassed over the collar 2 before the hub 4, together with its differentparts, is placed upon the axle.

It will be understood that in order to place the disk or ring 14 in theposition illustrated in Fig. 1 it will be necessary to form the ring ordisk in parts, so that the parts when disconnected can be placed aroundthe axle and what might be termec back of the flange 2. After thedisconnected parts of the ring 14 have been placed in proper positionthey are connected together by means of screws 16 or their equivalents,thereby constituting a continuous ring or disk.

For the purpose of properly closing the opening at the rear or inner endof the coupling-nut 11 the disk 14 is provided with thenon-screw-threaded portion 17, which nonscrew-threaded portion is formedof a diameter less than the diameter of the screw-threaded portion 18,as illustrated in Figs. 1 and 4.

After the sections of the disk or ring 14 have been properly connectedthe disk is connected to the coupling-nut 11 and constitutes a permanentpart of the nut 11.

After the disk or ring 14 has been placed in proper position withreference to the coupling-nut 11 the washer 20 is placed in the positionillustrated in Fig. 1, which washer should be an open one, so that itcan be properly connected or placed in its position, after which thecoupling-nut 11 is attached to the hub 4 by screw-threads, saidcoupling-nut being rotated until the flange 12 abuts against the innerend of the axle-box 3, thereby locking the nut 11 against rotation.

If in the event the disk 14 is not in proper position to securely holdthe hub against longitudinal movement, said disk is adjusted by rotationuntil it is brought into proper position to hold the hub andcoupling-nut against any longitudinal movement, but leaving the hub freeto rotate, it being understood that the disk or ring 14 should be soadjusted to produce the desired frictional contact.

After the disk or ring 14 has been properly adjusted and to prevent anyaccidental displacement of said disk or ring the set-screw 21 or itsequivalent may be employed to prevent any rotation of the ring or disk14 independent of the coupling-nut 11. However, I do not desire to beconfined to the special setscrew 21 herein shown or its location, as theonly object is to provide means to firmly hold' the ring or disk 14 inrelative position with the coupling-nut 11.

It will be understood that the set-screw 21 or other equivalent deviceis to be brought into use only after the proper and desired adjustmentof the ring or disk 14 has been made.

It will be understood that by providing means for adjusting the disk orring 14 within the coupling-nut 11 provision is made for washers ofdifferent thickness and at the same time taking up any wear of the samefrom use.

The hub 4 is closed at its outer end, and by spacing the hub from theaxle-box an oil-reservoir is provided which will contain sulficientamount of oil for a considerable length of time, as it will beunderstood that no oil can escape from the inner end of the hub, thatthe oil will be retained by means of the washers 19, 20, and 22, thewasher 22 being located between the inner face of the collar 2 and theinner abutting end of the axle-box 3.

For the purpose of providing means for adjusting the disk or ring 14 thesections composing said ring may be provided with the apertures 23,which will receive a pronged wrench.

I do not, however, desire tobe confined to the peculiar manner or way ofadjusting the ring or disk, but have described one way in which it maybe adjusted.

The washer 19 is located against the outer face of the annular flangeformed upon the inner end of the axle-box and the open end of the huband is so located for the purpose of preventing the escape of oil fromthe oilchamber.

Having fully described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a hub and an axlebox located therein, an axleprovided with a fixed collar, a coupling-nut having a differentiatedinner diameter, said differentiated inner diameter provided withscrew-threads,

a hub-retaining disk or ring having a screwthreaded periphery, and saidring or disk carried by the coupling-nut and located upon the outer faceof the collar of the axle, and means for locking the retaining-disk infixed adjustment with the coupling-nut, substantially as and for thepurpose specified.

2. The combination of a hub and an axlebox located therein, an axleprovided with a fixed collar, a coupling-nut having differentiated innerdiameters, said. differentiated inner diameters provided withscrew-threads, a divided hub-retaining disk or ring havingscrew-threaded periphery, and said divided ring or disk carried by thecoupling-nut and located upon the outer face of the fixed collar of theaxle, substantially as and for the purpose specified.

3. A hub closed at one end and open at its opposite end, an axle-boxfitting in and. interlocking with said hub and provided with an annularflange, a coupling-nut secured to threaded periphery, and said ring ordisk carried by the coupling-nut and located upon the outer face of thefixed collar of the axle, substantially as and for the purposespecified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two Witnesses.
